Inverse problem of the theory of electromagnetic radiation
Abstract
A method for calculating the trajectory of an arbitrarily moving charged particle from the radiation produced by the particle is discussed. The formula proposed by Feynman is used. In the far-field (radiation) approximation, the electric field vector moves in a plane orthogonal to the unit vector. Thus its specification determines only two independent scalar functions of time. In order to determine all three coordinates of the charged particle, either an extra condition must be imposed or the field intensity in one direction must be known. The problem of deducing the trajectory is of interest in astrophysics and in plasma diagnostics.
